An online forum for exploring the conceptual foundations of quantum mechanics, quantum field theory and quantum gravity

Daniel Rohrlich Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” In 1964, John Bell proved that quantum mechanics is “unreasonable” (to use Einstein’s term): there are nonlocal bipartite quantum correlations. But they are not the most nonlocal bipartite correlations consistent with relativistic causality (“no superluminal signalling”): also maximally nonlocal “superquantum” (or “PR-box”) correlations are consistent with… Read more →
